To all whom i! may concern:

Be it known that I, WILLIAM B. HAYDEN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Electrical Sparking Devicesfor Explosive-Engines, of which the following is a specification. I

This invention relates to electrical sparking devices for explosiveengines, and aims to provide a device of such class in a manner ashereinafter set forth, withelectricallyoperated means for moving anelectrode to and from contact with another electrode, both of which arein a spark circuit, thereby creating the ignition spark. The circuit foroperating the said means, which is termed the main circuit, communicateswith a single source of electrical energy while the spark circuitcommunicates with two sources of supply, one of which is the source forthe main circuit. The main circuit is opened and closed during theoperation of the engine by the timing device or the circuit-making andbreaking means carried by the engine, while the spark circuit is openedand closed owing to the actuation by the electri calYy-operated means,of a movable electrode which intermittently engages with a fixedelectrode, thereby creating the ignition sparks. v

The invention further aims to provide the device with me'ans to formwhat may be termed a starting circuit for initially throwing intooperation said electrically-operated means, forming an ignition spark,thereby igniting the explosive mixture in the combustion chamber of theengine, causing the explosion of such mixture and the operation of theengine; consequently causing the intermittent operation of the timingdevice or ci rcuit-making and breaking means carriedby the engine,thereby creating the ignition sparks. The said starting circuit whenclosed so as to create the spaik, owing to the-actuation by.theelectrically-operated means of the movableelectrode', overcomes thenecessity of cranking motor boat, the closing of the startingcircuitcuables the operator to readily start the engine without any in--convenience, as is generally the case at present.

The invention further comprises in its construction a plug set up insuch manner that'the movable parts When used for a'motor vehicle 01"thereof can be kept in a state of lubrication owing to the fact that thebearings for the said movable parts are arranged away from the heat ofcombustion in the cylinder of the engine.

The invention further aims to provide an electrical sparking device forexplosive engines which shall be extremely simple in its construction,readily positioned with respect to the cylinder of the engine, eflicientin its use and operation, strong, durable, obtaining an in- I tensifiedignition spark, easily set up in operative position, requiring nocomplicated wiring, compact, enabling an operator to obtain what may betermed the initial spark, in a convenient manner and comparativelyinexpensive to manufacture.

With the foregoing and'other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts hereinaftermore specifically described and illustrated in the accompanyingdrawings, which form a part or" this specification, and wherein is shownthe preferred embodiment of the invention; but it is to be understoodthat changes, variations and modifications can be resorted to which comewithin the scope of the claims hereunto appended.

In describing the inyention in detail, reference ishad to theaccompanying drawings, wherein like reference characters denotecorresponding'parts throughout the several views, and in which:

Figure 1 is a side elevation of a sparking device in accordance withthis invention, with the circuit connections removed; Fig. 2 is a topplan; Fig. 3 is a section on j line 3-3, Fig. 2; Fig. 4 is a section online 4- 4, Fig. 2; Fig. 5 is a perspective vie/w of a movable electrodeand shifting means therefor, theparts being disassembled, and Fig. 6is'a diagrammaticai view of a sparking device in accordance with thisinvention, showing the circuit connections.

'An electrical sparking device for explosive engines in accordance withthis invention, comprises a sectional hollow plug open at one end andclosed at its ether end, the inner or 0 en section bein indicated is r Pg I the reference character 1, ano the outer or closed section indicatedby the reference character 2. The sec in 1 is open from end to end, 15exteriorly screw-- threaded, as at 3, and at one end is providil with aprotuberance 4 which is slitted to receive a'contact point 5, preferablyconstructed of platinum. The protuberance 4 is arranged at the lowerportionof the section .1, and the said protuberance 4i withthe contactpoint 5 forms a fixed electrode. The section 1 is adapted to be screwedinto the enginercyglinder 8 so thafthefixed electrode will project intothe combustion chamber of tlie engine and cooperate with a vibratoryelectrode to be hereinafter referred to, said vibratory electrode alsoprojecting into the combustion chamber oi the engine. Holdfzlst means,as at 7, is provided upon the section 1 which abuts against the cylinder6 so as to prevent the looseningbf the section 1. The outer end of thesec tion 1 is formed with a plurality of apertured ears or lugs 8, for apurpose to be hereinafter referred to. The section 2 of the plug has itsouter end closed and its inner end open, and the said section 2 ishollow and provided with apertured lugs or protuberances 9 of the samecontour as the aportured ears or lugs 8. The section 2 is adapted to besecured to the section 1 through the medium of the hold fast devices 10extending through the apertured ears 8 and 9, and the two sections 1, 2are insulated. from one another through the medium of the insulatingmaterial 11 which is interposed between the inner ends of the saidsections and clamped between the same by the holdiast devices 10. Anysuitable form of insulating material may be employed. Although thesections 1, 2 are provided with apertured ears or lugs which receiveholdiast devices forconne'cting said sections with one another, yet anyother suitablemeans for this purpose can be employed, and although thesections 1 and 2 are shown substantially square in contour, yet the samemay be of any suitable shape. The section 2 is provided atone side withan opening closed by a removable plug 12. By such an arrangement, accesscan be had to the interior of the section 2 for cleaning it, or forother purposes.

The reference character 13 denotes an electro magnetic device which issuspended in close prcximity to the closed end of the section oftheplug, and the said cult-wire 23 and leading from the post 19 to theelec-' device 13 is suspended through the medium of a casing 14 which issuitably connected to the device 13; and

- the casing 14 is formed with an arm 15 secured upon the section 1 bythe holdfast devices 16 and provided with a vertically-extending portion17, to which binding posts l8, 19 are connected but insulated therefrom.From the post 18leads the wire 21 to the magnet, and from the magnet tothe post 19 lead the wire 20. Leading from the electrical source 22 tothep'ost 18, is a cirtrical'source 22 is a circuit wire 24. interposedin the circuit wire 23 is the timing or circuit-making and breakingdevice 25 which is carried by the engine. ln-

terposed in the circuit Wire 23 is a suitable switch 26. The armature ofthe magnetic device is indicated. by the reference character 27, and isprovided with a depending arm 28 carrying an adjustable lilting screw29,

l the function of which will be hereinafter referred to;

downward movement of the armature.

I irom a point in the section 2 of the plug through the section 1 of theplug, is arranged within the said section so it will not contact witheither of them, and has that end which is positioned in the section 2suitably connected,

as at 35-, to the inner end of a rock-shaft 36 which is mounted in onewall'ol the section 2 and in the bearing arm 37 which projects laterallyfrom one side of thescc' tion 2. The inner end of the shaft 36 isprovided with a bifurcated head 38 having a screw-threaded recess "38,and the said bifurcated head 38 is adapted to receive one end of the arm33, the latter being provided with an opening 38 through which extends aholdiast means 38, the said holdfastmeans 38 engaging in thescrew-threaded recess 38", thereby securing arm 33 to the head 38 of theshaft 36. The head 38 bears against the inner wall of the section 2 andacts as a means to prevent leakage through the opening in the section 2in which is mounted the shaft 36. Fixed to the rockshaft 36, through themedium of a pin 38 is a sleeve 40 recessed, as at 40, to form a pocketto receive a spring 40 which also engages in a pocket formed in theouter face of the side wall of the section 2 through which the shaft 36extends. The spring 40 acts as a means to re tain the head 38 againstthe wall ofthe section 2.' The sleeve 40 is provided with alongitudinally-extending actuating arm 41 which isof such length as toextend over the adjustable lifting screw 29 so that when the armature 27is elevated, the screw 29 will engage the arm 41 and rock the shaft 36,thereby shifting the movable electrode against the fixed electrode. Theelectrodes are normally retained separated through the medium of anadjustable compression spring 42 mount? ed upon the arm 41 and engagedby an adjustable member 43 carried by the arm 15, the latter beingprovided with an offset to receive the said member 43. The tension ofthe spring 42 is regulated through the medium of the adjustable member43. i

The main circuit is formed by the circuit wire 23 ironrthe electricalsource to binding post 18, branch wire 21 to magnet 13, through themagnet, thence to binding post 19 and circuit wire 24 to source 22. Thetiming or circuitmaking and breaking device 25 and switch 26, as beforestated, are interposed in the circuit wire 23.

With the electrical source 22 is coupled, as at 22*, an electricalsource' i. The two sources of supply 22 and 44 are in the sparkingcircuit and the said circuit is formed by the coupling 22, and circuitwire 45 leading to a non-vibrating coil 46. From the coil 46 leads abranch wire 47 to the engine bed 48, through the engine bed 48 to fixedelectrode, through vibratory electrode, section 2, binding post 48,circuit wire 49, part of wire 24, thence to coupling 22. Theinterposition of the non-vibrating coil 16 acts as a means to intensifythe spark, as will be evident. The non-vibrating coil may be of anysuitable construction.

From the arrangement of the circuits it will be evident that the maincircuit is somewhat weaker than the sparking circuit as it embodies buta single electrical source, consequently as the sparking circuit embodies the two-fold source of electrical energy, the

scones making and areal words, the spark will not be suede until themain circuit is broken. The plug when set up lias'only a. portion oi thescrew-threaded section l. extending in the cylinder, the section 2 beingin 2. position at a point removed iron: the cylinder and by sucharrangement,

it is evident that the movable parts or the plug and engine so as tobring the elements of the timing or.

circuit rnaking and breaking device into contact to form initial spark,starting circuit is provided.

which is independent of the main circuit, and which is adapted toenergize the magnet so as to form the initial spark. This startingcircuit comprises a switch in the form oi an ordinary push-butt0n, themovable member of which is indicated by the reference character 50, andthe fixed member by the reference char actor 51. The push-button isinterposed in the circult wire connection 52, leading from an electricalsource 53 to the circuit wire 23, and-leading from the vice can beunderstood from the foregoing descrip tion, taken in connection with theaccompanying drawings, but it will be s te ted that whe'nthe electromagnetic device is energized, the armature 27 will be attracted;consequently moving the contact points 5 and 34 together. When themagnet is-denergiZed,

the action of the spring 42 will causethe contacts 5 and 34- toseparate, thereby creating a spark. The

energizing end deenergizing oi'the magnet 13 will be had while theengine is running, and owing. to the action of the movable electrodewith respect to the fixed electrode, it will. be evident that thesparking circuit will be intermittently closed and opened;'

consequently intermittently creating an ignition spark which will beintensified owing to the interposition of the soft core coil ornon-vibrutingcoil, or what may be termed a primary current coil. Theinitial energizing oi the magnet so as to form the initial spark is bad,as before stated, owingto the operation in one direction of thepush-button, thereby ,closing the starting circuit which will remain insuch condition untilpressure is removed from the push button, thisformins' the initial seer- I .J r
